See below. I found the numbers from the printer's admin interface and they are somewhere in the middle.

I'm kinda used by now to > print-every-time-at-the-same-quality of the Laser world :-) I think we have that printer for about 18 months now. Here is the usage report straight from the printer's web interface: Cartridge Number used Black 4 Yellow 3 Light Cyan 1 Cyan 2 Light Magenta 2 Magenta 3 That's over a total page count of 1678, 6 of them on photo paper and the rest on plain. All 1672 plain papers were A4 size. BTW my wife sometimes re-use the other side of printed paper and I don't recall this has caused problems. The expiration period on most cartridges seem to be 2 years. The current Light Cyan cartridge was installed 26-8-2008 and will expire on 24-9-2010. I guess since it's the first Light Cyan cartridge that this is about the time we bought the printer (i.e end of August 2008). The Cyan cartridge is close to empty, but even if we had to change it today we still used it for 3-4 months longer than the Magenta or Yellow, which were replaced around last November. No problems about extended non-use periods (e.g. when we visited Israel for 5 weeks). Not aware that we had to clean the heads any time. Hope this helps, --Amos PS - Browsing around the printer's interface I noticed a neat "webscan" feature, which allows you to scan a document and download it completely through the printer's web interface, without having to install any software on the computer. _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
